During the summer of 1981, Oregon State University archaeologically tested three prehistoric sites on the William L. Finley National Wildlife Refuge. Among the sites tested were typical Willamette Valley floodplain and adjacent upland sites. Most settlement-subsistence pattern models proposed for the Willamette Valley have been generated with data from the...
It has been hypothesized that horizontal gene/chromosome transfer and parasexual recombination following hyphal fusion between different strains may contribute to the emergence of wide genetic variability in plant pathogenic and other fungi. However, the significance of vegetative (heterokaryon) incompatibility responses, which commonly result in cell death, in preventing these processes...
Oomycetes form a deep lineage of eukaryotic organisms that includes a large number of plant pathogens which threaten natural and managed ecosystems. We undertook a survey to query the community for their ranking of plant-pathogenic oomycete species based on scientific and economic importance. In total, we received 263 votes from...

In broiler chickens, hepatic lipid metabolism plays a significant role in whole body and muscle fatty acid (FA) incorporation. Flax seed is a rich source of α-linolenic acid and can be used to increase n-3 FA in poultry meat. Previous studies have shown that flax seed in combination with carbohydrase...
Flaxseed is a rich source of alpha-linolenic acid (ALA). Feeding laying hens flax seed can increase n-3 fatty acids content (FA) in eggs, thus increasing human intake of n-3 FA. However, non-starch polysaccharides (NSP), which decreases digestibility of dietary lipids and proteins. Addition of carbohydrase enzymes to flax-based layer diets...
The use of an antibiotic as a growth promoter (AGP) began in the 1940’s with the discovery of growth responses from Streptomyces aureofaciens in the monogastric diet. However, resistance and residue problems have increased the negative consumer perception of growth promoting antibiotic use in animal diets. Although no direct link...
Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...
